You may possibly find other missing tools as you go along. This is why in the wiki there is a link to a page called "Required Packages": <blockquote><a class="moz-txt-link-freetext" href="http://www.x.org/wiki/RequiredPackages">http://www.x.org/wiki/RequiredPackages</a> </blockquote> It lists all the packages you need to install in order to build all of X. This list varies greatly from one OS to another. If you'd like to make a contribution to the wiki and write down the packages you installed on centos, that would be great. Just follow the pattern in there. I wrote the ones for Ubuntu. On a freshly installed distro, I can build all of X with just three commands. One to install the list of tools, one to create the installation dir and one to run build.sh. Thanks </body> </html>
